What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo investigate the value of baseline CT imaging for the prediction of functional outcome and benefit of endovascular thrombectomy (EVT) for anterior large vessel occlusion (LVO). MATERIALS AND
methodsWe used individual patient data from seven randomized EVT trials and included patients with available baseline CT imaging and outcome data. We developed a model to predict functional outcome and benefit of EVT, including baseline stroke-related and brain frailty CT imaging features alone. We compared the discriminative performance of our model for predicting good functional outcome (modified Rankin Scale [mRS] 0-2) and treatment benefit (difference between the probability of mRS 0-2 with vs without EVT) with MR PREDICTS by calculating the difference in C-statistics (delta C and delta C-for-benefit).
resultsWe included 1391 patients (median age, 67 years, interquartile range 59-76; 53% male). Discrimination of the model based on CT imaging alone was substantial for the prediction of good functional outcome (C-statistic 0.700, 95% CI: 0.666-0.731) and treatment benefit (C-for-benefit 0.640, 95% CI: 0.586-0.690). After adding the known strongest clinical predictors namely age and National Institutes of Health Stroke Scale score, discrimination improved to slightly lower than MR PREDICTS for prediction of good functional outcome (C-statistic 0.733 vs 0.750; delta C, -0.017 [95% CI: -0.037 to 0.003]) and treatment benefit (C-for-benefit 0.675 vs 0.692; delta C-for-benefit -0.017 [95% CI: -0.084 to 0.050]).
conclusionsBaseline CT imaging holds considerable predictive value with regard to functional outcome and treatment benefit, but a combination of clinical and imaging features offers the best predictive performance. KEY POINTS: Question The predictive value of baseline CT imaging for the prediction of functional outcome and benefit of EVT for anterior LVO stroke is uncertain. Findings Discrimination of a model based on CT imaging alone is substantial, but can further be improved by the addition of limited clinical characteristics. Clinical relevance Baseline CT imaging holds considerable predictive value with regard to functional outcome and treatment benefit. The addition of limited clinical information is needed to achieve predictive performance similar to an established prediction model.
